“…The average pH for both treatment wetlands systems and phases ranges between 6.9 and 7.5, and therefore, classified as neutral, although significant differences ( p < 0.05) can be found between the two phases for the two treatment wetlands systems. However, values between 6.0 and 8.0, similar to those found in this study, have been reported by other authors for VSSF TWs planted with ornamental and common plants species [ 14 , 36 ]. Thus, pH values are not expected to affect the removal process for organic matter (COD), nutrients (NH 4 + -N and PO 4 −3 -P), and plant development [ 37 ].…”

The aim of this work was to evaluate the performance of vertical subsurface flow treatment wetlands (VSSF TWs) for treating rural domestic wastewater when strategies such as bed depth reduction and media change are used in combination with bottom saturation. Two treatment wetland systems were implemented: normal (VF-N), with a bed depth of 1.0 m, and modified (VF-M), with a bed depth of 0.5 m and a bottom layer of natural zeolite. Schoenoplectus californicus was used as experimental plant. These two treatment systems were operated at a hydraulic loading rate of 120 mm/d in two phases. Phase I did not use bottom saturation, while Phase II involved a bottom saturation of the zeolite layer of the VF-M system. The results show that bed depth reduction did not have a significant effect (p > 0.05) in terms of organic matter, solids, and ammonium removal. Conversely, it had a significant influence (p < 0.05) on phosphate as well as a negative effect on pathogen removal. This influence could be explained by initial media capacity for phosphorus removal and filtration importance in the case of pathogens. Partial saturation only had a positive influence on total nitrogen removal. The addition of a bottom layer of natural zeolite showed no positive effect on nutrient removal. The plant showed adaptation and positive development in both VF-N and VF-M. The water balance showed that water loss was not influenced by bed depth reduction. Therefore, according to the previous results, a combination of the proposal modifications to VSSF TWs can be introduced for treating rural domestic wastewater.

“…During the study, I.pseudacorus showed significant growth (plant height, paired T-Test, p < 0.05) and also produced flowers). I.pseudacorus had showed good performance in dealing with greywater in a previous study (Perdana et al, 2018). Similar results were also found for Caladium bicolor and Rhoe discolor which encountered good growth but no flowering occurred.…”

This original research examines a full-scale subsurface Constructed Wetland (CW) system in Indonesia, where most CW research has been limited to laboratory scale experiments. The CW system was located in Bali and built in 2015 in a single series formation. This study aims to demonstrate the performance of the system in treating greywater and examine the nutrient content plants’ above-ground biomass. The CW was arranged in linear sequence composed of one unplanted (CW1) and five planted treatments of Iris pseudacorus (CW2), Caladium bicolor (CW3) , Rhoe discolor (CW4) , Sansevieria trifasciata (CW5) and Heliconia psittacorum (CW6). There has been little research on Caladium bicolor, Rhoe discolor and Sansevieria trifasciata in a full-scale CW application. Our results showed fluctuating efficiency (%) in the reduction of Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solid (TSS), Oil and Grease (O&G), Nitrate and Phosphate. The highest removal efficiency for CW1, CW2, CW3, CW4, CW5, CW6 were O&G (63.63%), BOD (90.66%), Nitrate (83.55%), BOD (80%), BOD (82.88%) and Phosphate (89.93%) respectively. After the experimental period, S. trifasciata and H. psittacorum experienced a decrease in Total N concentration, while H. psittacorum experienced a decrease in phosphate in above-ground biomass. Species of R. discolor, C. bicolor and I. pseudacorus showed good performance in terms of their growth and development. Although high removal efficiency was observed at certain times, this study showed the negative removal efficiencies at times among parameters as a consequence of the low Hydraulic Retention Time (HRT) and high Hydraulic Loading Rate (HLR).

The increase in urban solid waste has become a massive burden on society resulting in the environmental and economic problems, particularly in terms of poor solid waste management (Luo et al., 2020). Ninety-five percent of urban solid waste worldwide is disposed of in landfills (Gao et al., 2014). Landfills provoke several risks, as wastes may release harmful elements into the environment. The leachate from landfill remains a critical problem, because it may pose a threats to land, surface water, and groundwater (Yan et al., 2015). Factors such as area conditions, age, type of waste, and operation of the landfill can vary the content of the landfill (Fang et al., 2017). Countries with tropical climate produce more organic wastes (Idris et al., 2004). The content of organic substance in wastewater is represented by the values of Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD). The BOD and COD values are used to determine the degradation rate of landfill leachate (Barlaz et al., 2002;Borglin et al., 2004). The values of BOD/COD leachate ratio in tropical regions are 0.03-0.74 higher than in other regions. In general, the BOD/ COD ratio values in tropical regions are BOD> 100 g/m 3 and COD> 500 g/m 3 in landfill leachate. Bakhshoodeh et al., (2020) showed that the content of organic substance in leachate is toxic to microbial activities.Conventional leachate processing is classified into three major groups, those are 1) chemicalphysical process, 2) biological process, and 3)
